Abstract
Abstract 57 Heavy hydrocarbon oils of high paraffin content are catalytically cracked using zeolite beta. The paraffin content of the oil is at least 20 weight percent or higher. The gasoline cracking products have a high octane rating and the higher boiling products a decreased pour point resulting from the dewaxing activity of the zeolite beta.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
84 words
A process for catalytically cracking a hydrocarbon oil having an initial boiling point above 200 0 C comprising contacting the oil with a circulating hot cracking catalyst in the absence of added hydrogen to produce cracking products which are separated from the catalyst, and continuously regenerating the catalyst on a cyclic basis by oxidative removal of the carbon deposited on the cracking catalyst during the cracking, characterised in that feedstock comprises at least 20 weight percent paraffins and the cracking catalyst comprises zeolite beta.
Claim 2
Dependent Claim
84 words
A process for catalytically cracking a hydrocarbon oil having an initial boiling point above 200 0 C comprising contacting the oil with a circulating hot cracking catalyst in the absence of added hydrogen to produce cracking products which are separated from the catalyst, and continuously regenerating the catalyst on a cyclic basis by oxidative removal of the carbon deposited on the cracking catalyst during the cracking, characterised in that feedstock comprises at least 20 weight percent paraffins and the cracking catalyst comprises zeolite beta.
Claim 3
Dependent Claim
20 words
A process according to claim 1 in which the feedstock boils within the range of 300 to 500 0 C.
